The future of email deliverability is increasingly intertwined with the advancement of artificial intelligence (AI) and machine learning (ML) in spam filtering. As AI systems become more sophisticated, they are reshaping how emails are evaluated, delivered, and perceived by recipients. This evolution demands that email senders adapt their strategies to align with these intelligent filters, focusing on user engagement, content relevance, and technical compliance to ensure their messages reach the inbox.
Key findings
AI-driven filtering: AI's advanced algorithms are capable of learning and adapting to new threats in real-time, moving beyond simplistic keyword-based filtering.
Predictive accuracy: Neural networks are being developed to predict with high accuracy how users will interact with an email even before it is sent, affecting inbox placement.
Transparency in filtering: There's a potential for more legislation around making AI/ML decision-making in general less opaque, which could indirectly impact spam filtering services.
Evolving spam tactics: Spammers will also leverage AI to craft more convincing messages, attempting to bypass traditional and even AI filters.
Data sharing: Increased data sharing between AI systems (e.g., between senders' AI and ISP's AI) is likely to drive even greater accuracy in deliverability predictions.
Key considerations
Adapting to AI filters: Senders must have a better understanding of what to expect from AI filters and act accordingly to maintain good email deliverability. This includes understanding the various factors influencing email deliverability.
Focus on engagement: With AI predicting user interaction, the focus will shift even more towards sending highly relevant and engaging content that encourages positive user signals.
Proactive diagnostics: Regular monitoring and diagnosing deliverability issues will become crucial to stay ahead of AI-powered spam detection. This includes understanding what AI in the inbox means for your strategy.
Combatting sophisticated spam: The ongoing arms race between legitimate senders and spammers will continue, necessitating constant vigilance and adaptation to new spammer tactics.
What email marketers say
Email marketers are keenly aware of the growing influence of AI on email deliverability, often viewing the present challenges as a preview of the future. Their perspectives highlight the need for more intelligent campaign strategies that anticipate user behavior and adapt to the increasingly sophisticated methods of spam detection. Many marketers emphasize the importance of relevance, consent, and avoiding tactics that resemble spam, particularly in cold outreach.
Key opinions
AI as the present and future: Many marketers believe that the future of deliverability is already here, with AI filters being a significant part of the current landscape.
Predicting user interaction: There's a strong belief that AI will enable highly accurate predictions of how recipients will engage with emails, influencing content and timing.
Cold outreach challenges: The increasing annoyance and filtering of anonymous cold outreach is a significant concern for marketers relying on such strategies.
Spammer tactics adaptation: Marketers note that cold outreach efforts often employ spammer tactics, making them difficult to stop with traditional filtering methods.
Newsletter resurgence: Email newsletters are seen as a robust content marketing medium that will continue to thrive.
Key considerations
Content and template optimization: Marketers need to optimize email templates and content to be AI-friendly, moving beyond the concern of spam trigger words.
Understanding AI's interpretation: Utilize AI tools to simulate how spam filters evaluate email content and predict spam scores, as suggested by experts in optimizing deliverability with AI.
Ethical considerations: Marketers should prioritize user consent and avoid deceptive practices, as AI filters become better at identifying unwanted mail.
Staying current: Continuously educate themselves on the latest AI trends in email filtering to adapt strategies proactively.

What the experts say
Experts in email deliverability recognize that AI's growing role isn't just about technical filtering; it's also about a shift towards greater transparency in how filtering decisions are made. They foresee a future where compliance and proper authentication become even more critical, as AI systems become adept at identifying subtle patterns of unwanted mail and evasive tactics. The consensus is that foundational elements of email, like DNS records, will remain paramount.
Key opinions
Increased transparency: There will be more legislation and industry initiatives (like Verizon's feeds) pushing for less opaque AI/ML decision-making in spam filtering.
Prevalence of TXT RRs: Experts confidently predict an increase in DNS TXT records, indicating a growing reliance on various DNS-based authentication and reputation mechanisms.
AI for wanted mail only: AI systems will evolve to learn enough to enable the deliverability of only the mail that users genuinely want to receive.
Spammers' AI adoption: As AI becomes more sophisticated, spammers might use it to craft more convincing spam messages that can bypass even advanced filters.
Cold outreach as a deliverability issue: The continuous adoption of spammer tactics by cold outreach campaigns means receivers struggle to stop unwanted mail, making it a persistent deliverability problem.
Key considerations
Strengthening authentication: The increasing sophistication of AI filters means that fundamental email authentication protocols like DMARC, SPF, and DKIM will become even more critical for establishing sender legitimacy.
Monitoring blocklists and reputation: With AI's ability to quickly identify and react to suspicious activity, regular blocklist monitoring and managing sender reputation (even on dynamic AI systems) is paramount.
Adapting to AI-generated spam: Senders must be prepared for an environment where AI is used by both sides, requiring more sophisticated content and engagement strategies to stand out from AI-crafted spam, as explored in articles like The evolution of spam: the future and generative AI.
Compliance and ethics: As transparency increases, adherence to privacy regulations and ethical sending practices will become even more heavily scrutinized by AI systems.
Expert view
Expert from Email Geeks believes that the future of deliverability will involve AI learning enough to ensure that only the mail the user truly wants is delivered to their inbox. This implies a highly personalized and effective filtering mechanism.
